Question

You move five electrons through a potential difference of 5.00 V. How much work does this require?

Answer 1

Answer:

As potential difference (V)= 5Volt

Total electrons =5

As potentail diffference =work/amount of charge

V=W/Q

The amount of charge=?

The quantisation of charge=

Q=ne

=5*1.6*10^-19

Amount of charge=5*1.6*10^-19

NOW WORK=

W=V*Q

=5*5*1.6*10^-19

=25*1.6*10^-19joules

WORK=25*1.6*10^-19J
